Abstract

Disclosed is a transparent vacuum bag, which comprises a bag body which is made of polyethylene layer. The utility model is characterized by comprising a PA reinforced nylon layer and an antistatic layer. The outer layer of the polyethylene layer has an inner layer of the bag body which is made of the PA reinforced nylon layer through drying composite adhesion. The inner and the outer surfaces of the inner layer are coated with the antistatic layer, which provides the transparent vacuum bag which is made of the composite structure and is applied in the outer package of an electronic equipment or an element piece, thereby the transparent vacuum bag has good thermal stable property, tensile strength, better moisture proof, waterproof and oxygen proof after extracted into vacuum and good antistatic effect.

Description

The transparent vacuum bag

Technical field

The utility model relates to a kind of packaging bag, and particularly a kind of transparent vacuum packaging bag belongs to the laminar product field.

Background technology

Along with the prosperity of electron trade, the packing of the product components and parts of electronics, computer and communication aspect is still used the common packaging bag of tradition, the sack that the blowing of for example present widely used PE (polyethylene) material is made mostly.Though still because the character non-refractory of PE (polyethylene) material is promptly inflammable, tensile strength is not high yet more can not to vacuumize this packaging bag withstanding corrosion, plays comprehensive special quality protective effect so can't internally adorn product.

Summary of the invention

The purpose of this utility model is: the defective that remedies above-mentioned technology, the transparent vacuum bag that provides a kind of composite structure to make, be used for the external packing of electronic machine or components and parts, have good temperature resistance and tensile strength, and can vacuumize so that better play the effect of protection against the tide (being the water proof oxygen barrier) and have the good anti-static effect.

The purpose of this utility model is achieved in that a kind of transparent vacuum bag, comprise the bag that constitutes by polyethylene layer, it is characterized in that the described PA that also comprises strengthens nylon layer and antistatic backing, the PA that the one side of polyethylene layer is provided with by the dry type compound sticking strengthens nylon layer, and the another side that the another side of polyethylene layer and PA strengthen nylon layer scribbles antistatic backing respectively.

Described PA strengthens the PET polyester layer that can have additional between nylon layer and the antistatic backing by the dry type compoiste adhering.

Described polyethylene layer is that PE contains the metallocene PE layer.

The metallocene content that described PE contains in the metallocene PE layer is 30%.

Advantage of the present utility model is:

Bag of the present utility model adopts four layers or five layer material structures, make the bag after making have good temperature resistance and tensile strength, the most significant advantage is can vacuumize so that better play the effect of protection against the tide (being the water proof oxygen barrier) and have the good anti-static effect.In addition, good diaphaneity makes the client can distinguish clearly that the content product especially help on the article scanning of bar code to read.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the schematic cross-section of the utility model four-layer structure;

Fig. 2 is the schematic cross-section of the utility model five-layer structure.

Among the figure 1 is the polyethylene layer that PE contains metallocene; The 2nd, PA strengthens nylon layer; The 3rd, the PET polyester layer; The 4th, antistatic backing.

The specific embodiment

Accompanying drawing is non-limiting to disclose two specific embodiments of the present utility model, and the utility model will be further described below in conjunction with accompanying drawing.

Embodiment 1: as shown in Figure 1, it is that 30% PE contains the bag that metallocene PE layer 1 constitutes that the structure of the transparent vacuum bag of this four-layer structure comprises by metallocene content, the PA that the one side that PE contains metallocene PE layer 1 is provided with by the dry type compound sticking strengthens nylon layer 2, and PE contains the another side of metallocene PE layer 1 and another side that PA strengthens nylon layer 2 scribbles antistatic backing 4 respectively.

Embodiment 2: as shown in Figure 2, it is that 30% PE contains the bag that metallocene PE layer 1 constitutes that the structure of the transparent vacuum bag of this five-layer structure comprises by metallocene content, the PA that the one side that PE contains metallocene PE layer 1 is provided with by the dry type compound sticking strengthens nylon layer 2, the another side that PA strengthens nylon layer 2 is provided with the PET polyester layer 3 of using the dry type compoiste adhering, and PE contains the another side of metallocene PE layer 1 and the another side of PET polyester layer 3 scribbles antistatic backing 4 respectively.

Claims

1. transparent vacuum bag, comprise the bag that constitutes by polyethylene layer, it is characterized in that also comprising that PA strengthens nylon layer and antistatic backing, the PA that the one side of polyethylene layer is provided with by the dry type compound sticking strengthens nylon layer, and the another side that the another side of polyethylene layer and PA strengthen nylon layer scribbles antistatic backing respectively.

2. transparent vacuum bag according to claim 1 is characterized in that described PA strengthens the PET polyester layer that has additional between nylon layer and the antistatic backing by the dry type compoiste adhering.

3. transparent vacuum bag according to claim 1 and 2 is characterized in that described polyethylene layer is that PE contains the metallocene PE layer.
